General Accident/Commercial Union could have become "Commercial Accident", but that wasn't thought to be good PR. Fortunetely they were taken over by Norwich Union in the meantime so they went for "GNU". That didn't sound good either so they changed to "Aviva" as a corporate name after a while, keeping "Norwich Union" as the brand.
Royal Bank of Scotland have taken over many banks, but not always renamed them. They have left NatWest largely untouched (apart from the logo) - but they are listed as RBS Group on the FTSE.
Lloyds & TSB was rather straight forward for a bank at the time of their merger; perhaps it was important to keep the TSB name because it was previously government owned.
What would/will happen with HBOS & Lloyds-TSB though?



I have a feeling that even though they would keep BOS as a subsidiary (it's the oldest bank in Scotland and one with the right to produce bank notes) they would retain Scottish or Scotland somewhere else in the name.
Any other suggestions for the name?
